An electrochemical cell comprising a body of proton donor electrolyte in effective contact with first and second electrodes one of which consists essentially of a fullerene in contact with a conductive material. By the application of an electric current across the electrodes the cell can be used to hydrogenate the fullerene, thereby storing hydrogen and electric energy.
